88,000 BTU, 80% AFUE

The ACiQ N80ESN0901714A furnace has an input rating of 88,000 BTU. With its 80% AFUE efficiency, the furnace delivers an output of 70,400 BTU. The 80% AFUE indicates that 80% of the gas used is converted into heat for your home, while the remaining 20% is lost through the flue piping and normal furnace operations. Metal flue venting is required for 80% efficiency furnaces, and if you prefer plastic/PVC venting, a furnace with 90% efficiency or higher is necessary. Although this unit is initially configured for natural gas, an optional LP conversion kit is available at an additional cost. Please note that this furnace does not comply with Low NOx or Ultra Low NOx standards. If shipped to California, it may be subject to a mitigation fee.


ACiQ provides a 10-year limited warranty for parts and a 20-year limited warranty for the heat exchanger. To ensure the validity of the warranties for both parts and the heat exchanger, it is essential to register the unit with the manufacturer within 90 days of installation. Additionally, the installation must comply with state and local codes.

Installation and Durability

The ACiQ N80ESN0901714A furnace offers great installation flexibility, allowing for upflow, downflow, or horizontal configuration. Its sturdy outer casing ensures durability throughout its lifespan, providing the assurance that your home will remain comfortable all year round. Please note that this furnace is not suitable for standalone installation in mobile homes.

Questions and Answers

Customer Questions
Who makes ACiQ?
ACiQ air conditioning systems, standard heat pumps, and gas furnaces are manufactured by the largest HVAC manufacturer in America, who also happens to be the seller of the nation’s #1 brand. However, because our prices are SO LOW, they will not allow us to mention their name! They must protect their current market share where typical home systems retail between $15,000 to $25,000 for the identical equipment that we let you buy direct for under $3,000. We offer homeowners and contractors the highest quality and best warranty HVAC systems in the industry at the absolute lowest price. With our industry-leading, high-tech ACiQ equipment, your home and your savings just got a whole lot smarter!
What happens if this breaks down?
HVACDirect.com gives you lifetime tech support. Many common problems can be solved with a phone call to us. HVACDirect.com is an authorized dealer of ACiQ, therefore equipment we sell carries the full manufacturer's warranty. The warranty applies to all parts. You have to register the products online in order to extend the warranty to the full 10 years, otherwise the term is 5 years. If a part fails under warranty, you will not pay anything for the replacement part. Should a part fail under warranty, the first step is to have a professional confirm what part needs to be replaced. Then, contact us at customerservice@hvacdirect.com or by calling and asking for customer service.
What happens if it arrives damaged?
If you are present during drop-off and you see obvious signs of damage or rough handling in transit - please ask the driver to wait while you inspect the equipment. If it is damaged badly enough that you believe it can not function, you have the right to refuse the damaged portion of the shipment. If you discover the damage after the driver has left, take photos of the damage and send them to customerservice@hvacdirect.com. Please refer to your order number in the email. This starts the process and one of our representatives will be in touch with you promptly.
How can I find an installer?
It’s easier than you think – the key is to find an independent contractor or small company as opposed to a larger HVAC service. A one or two person outfit will do the work more quickly and cheaply than a bigger company, too. Yelp.com, Thumbtack.com, and Porch.com are websites are designed to help you connect with a professional in your area. You could also place a call to the last professional who did work on your home and see if they have any recommendations.
What's the warranty?
ACiQ’s 10 year Warranty (online registration required) is one of the top warranties available today.  Many of the higher-SEER units have even higher warranties and some of the higher efficient furnaces have longer heat exchanger warranties.
What size is flue pipe?
The flue size is 4". If you have any further questions, please call us and we will be happy to assist you.
Is this unit a natural gas appliance and if so do you send propane orifices so in can be used with propane?
Hello, yes this unit is natural gas. A propane conversion kit does not come included with the unit but it is an option extra that you can select on the product page. If you have any further questions please feel free to give us a call! Thank you.
Can this furnace be used in a downflow operation?
Hi, yes this unit can be used in downflow, upflow, and horizontal configurations. If you have any further questions please feel free to give us a call! Thank you.
